I've been using Suno for months and kept hitting the same wall: the Style of Music field is the most powerful parameter, but there's almost no guidance on how to use it well.

Too many words breaks it. Wrong order changes the feel. v4 and v5 respond completely differently to the same prompt — something that works great on v4.5 produces generic results on v3.

So I built Supre. You pick genre, mood, BPM, instruments, vocal style and which Suno version you're using — it generates a calibrated Style prompt specifically for that version.

Built with Claude Haiku on the backend, Vercel serverless, Upstash Redis for rate limiting.
